, PRESS FOR PRESSING CONCRETE INTO BLOCKS.

. Application filed August 1, 1907. Serial No. 386,?33.

To all whom it may concern:

Be it known that I, Exes S. Rmmoxn, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Presses for Pressing Concrete into Blocks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My inventionhas relation to new and useful improvements in presses for pressing concrete in blocks or bricks and has for its object the production of a simple a d economical press of this character having means whereby a great upward pressuremay be exerted on the press table with but little effort on the .part of the operator.

\Yith these and other ends in view that will appear as the nature of the inxention is better understood, my invention co sists in the novel construction, combination ndarrangemcnt of parts illustrated in the drawings and set forth in the specification and.

claims hereunto appended.

In the accompanying drawings in which like parts are designated by like characters throughout the several views :F igure 1 is a side elevation of my invention, part of the mold removed; Fig. 2 is a cross sectional view on the line 2-2 of Fig. 1; Fig. 3 is a cross sectional view of one of the pulleys, guide members. and transverse sliding beams, on the line 33 of Fig. 1; and Fig. 4 is a side elevation of the invention partly in section, showing a modified form of the mechanism for raising the press table.

My invention is described as follows The numeral 1 represents the base plate of the press, which is preferably provided with an opening 2. Secured to theupper face of said base plate near each corner is: an upright guide rod 3, terminating at its upper end in a thread 4.

Standards or bearings 5 are bolted or otherwise secured at their lower ends to said base plate near its side edges, and are pr0- vided near their upper ends and outer faces with pawls 6, the purpose of which will be shown.

A'iltll'lSVClSG shaft 7, is journaled near its ends in The upper ends of said upright bear ings or standards 5, and has rigidly connected to it, ncar each end and outward of said Specification of Letters Patent.

standards or bearings, a ratchet wheel'S. Said drive shaft is also provided near each end inward of said upright standards with a pinion 9, and near one end, out-ward the ad- Jacent ratchet wheel, with an operating lever 10.

Formed on the upper face of said base plate inward and adjacent the lower ends of said upright guide rods are vertical bearings 11, which terminate at their up )er ends in corresponding oppositely disposed ears or extensions 12, and pivoted at their lower ends between the said bearings 3 by a transverse )ivot rod 13 or other suitable means, are the lower ends of vertical oscillating links 14. By constructing said bearings 11 in this manner all danger of lateral displacement of said oscillating links 14 is obviated.

Loosely secured at their lower ends near the ends of transverse rods 15, rigidly secured to said oscillating links 1-1 about midway of their lengths are oscillating links 16, the upper ends of which are pivoted by transverse rods 17, or other suitable means, to the sides and near the corners of a horizontal press guide rods.

Rigidly secured at their outer ends to transverse rods 19 journaled' in the upper ends of said vertical oscillating links 14 are oscillating hnks 20, the inner ends of wlnch 'are loosely connected near the ends of a transverse drive rod 21, adapted to work in the slots of vertical guide links 22, secured below the press table in any manner desirable.

The numeral23 re )resents two vertical rack bars, which are located adjacent and adapted to be engaged by said pinions 9 of said drive shaft when my press is in operation. The upper ends of said vertical rack bars terminate in enlargements 24 by means of which said bars are connected near the ends of said transverse drive rod 21. Said enlargements also serve as bearings for said drive rod.

Should I find it desisable in the application Patented Aug. 4,1908.

table 18, suitably secured to said upright of my invention, 1 may dispense with said rack bars and pinion. 23 and 9, espectively, and substitute in lieu thereof a cable 25 which is secured at one end to said transverse drive rod 21, works over a pulley 26, journaled to the under face of said press table 18 or secured to guide rods 3, and is secured at its opposite end to and is adapted to wind.

around said transverse drive shaft 7.

justably secured to the upper threaded ends of said guide rods 3 by nuts 27 or other equivalent means is a suitable horizontal head plate 2 and securely bolted or otherwise secured to the under face of said head plate is a pressing plate 29 of any suitable form. Journaled to horizontal stub axles or shafts 30, extending inward from collars 31, adjustably secured by set screws 32 or other equivalent means to the foremost of said upright guide rods 3 above said )ress table 18, are pulleys 33. Horizontal inwardly-extending guide irons or members 34, having lateral openings 35 are adjustably secured to the rearmost of said upright guide rods 3 above the press table.

36 represents two transverse sliding beams, the rear ends of which work through the openings 35 in said guide irons or members 34. The front ends of said sliding beams 36 work over said mlleys A mold 37 of suitable form and having a suitable frame 38 is pivoted to the upper edges of said sliding beams in any suitable manner, and is provided with a removable side or part 39 ada )ted to be secured in proper position by bolts and nuts and a latch 40, pivoted to the fixed part of said mold.

In the application of my invention, the concrete or other material to be pressed into blocks or bricks is placed in the mold and the sliding beams 36 moved laterally until the mold is directly under said pressing plate :29. Said drive shaft 7 is then turned or rotated by applying power to said operating lever 10 when said )inions 9 through the medium of said vertical toothed bars 23 cause said drive bar 21 to move upward in the slots of said vertical guide links. During this operation, the inner ends of said oscillating links '20 are carried upward with said drive bar 21 until it is in a substantially horizontal position, causing the upper ends of said vertical oscillating links 14 to swing outward, which links, through the medium of said oscillating links 16, effect the ascension .of said press table.

18, the upper face of which engages the lower end of said mold frame 38 and presses the concrete or stone in the mold 37 against said pres ing plate 29. When the operator desires to remove the pressure from the concrete or stone in the mold, the press table 18 i lowered, when the finished concrete or stone may be removed from the mold by sliding said sliding beams :30 lat erally until the mold is out front under the pressing plate and tilting the mold over on one side.

I do not confine myself to any specific form of mold, but claim the right to use any form desirable, which form depends on the shape into which I desire to press the concrete or stone.

My invention is susceptible of various changes without departing from the spirit thereof. tj

From the foregoing description the construction and operation of my invention will be understood without a more expanded explanation.

Having described mydnyention, what I claim as new and desire to secure by Letters Patent, is:

1. A press of the character described, embracing a base, upright guide members mounted on the base, horizontally spaced pulleys mounted to slide on the front guide members horizontal inwardly projecting guide members having lateral guide openings, slidably mounted on the rear guide members, two horizontally spaced beams arranged to have their front ends work over the pulleys and their rear or op )osite ends through the guide openings of said guide members and a mold member pivotally mounted between said beam and arranged to swing in a plane at an angle thereto.

2. A press of the character described embracing an upright supportin structure,

a horizontally disposed )ress talile mounted to slide thereon, vertica y disposed oscillating links pivoted attheir inner ends below the press table, vertical op )OSlte disposed longitudinally slotted guide inks sustained by and below the )ress table, a horizontally disposed drive rod arranged for movement in the slots of the guide links, oscillating links forming a connection between the drive rod and upper ends of the vertically disposed links and oscillating means for connecting the vertical links with the press table with means for imparting movement to the drive rod to raise the table.

3. A press of the character described, embracing a supporting structure, a horizontally disposed press table slidably mounted therein, a horizontally disposed shaft rotatably sustained below the mess table, pinions fixed near the ends of the shaft, vertically disposed longitudinally slotted guide links sustained below the press table, a horizontally disposed guide member arranged to slide in the slots of the guide links, depending rack bars fixedly sustained by the guide member and being so positioned as to engage with said pinions, pivoted connections between the guide member and press table and means for imparting movement to he shaft to raise the table with means for maintaining the shaft against movement in a reverse direction.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
